Dr. Josh Davidson, an entrepreneur, educator and optometrist at Williamson Eye Center, discusses norms and expectations in preoperative prep for cataract surgery. He highlighted that 60-80% of cataract patients have ocular surface disease (OSD), which affects post-surgery satisfaction. Davidson emphasized the importance of treating OSD before surgery to prevent vision and safety issues. He noted that routine preoperative lab tests are unnecessary, citing studies that found no benefit. Davidson recommended tear osmolarity, MMP-9 tests, and staining for preoperative workups. He also stressed the need for optometrists to educate patients about surgical options and preoperative hygiene.
